Should be fine, pretty sure mine was used.

Will that tcu work in a LS ?

TreysGS460

It won't, unfortunately the LS has a different TCM size, so you can't even plug it it.

However, the f sport LS has one already.

Thanks for the reply, I know about the LS module but looking online it's the same part number as other models of similar years.I have read that you can't use that type of tcm with an awd f sport but I can't see why not? there must be something else involved for the rev matching etc.

I installed the ISF TCU today on the 10 GS460
part number 89535-53010. No more transmission lag. Power band is nice!

The only thing I noticed when holding down the trac button only one lamp illuminates on the right now on the dash when there was 2 illuminated before

I posted that video a few days ago on the GS460 facebook group, a lot of people liked it.

Loi tuned the GS and it runs great. Definitely drives more like an ISF. I installed the ISF Injen CAI & the ISF intake snorkel. Made a big difference

Sorry to bump thread, but can any year ISF TCU be swapped into the GS460?
Or does it have to be from the same model year.

I have a 2010 ISF TCU in my 2008 GS and it works fine. I havent heard of anyone having problems doing the opposite either.
